America's Battered Tanker Fleet Comes Home to Heal
After a deadly midair collision and months of combat damage over Iran, the U.S. Air Force's aging KC-135s are quietly being rebuilt in Oklahoma.

[1] The collision on March 12 killed the entire crew of the tanker with call sign Zeus 95. [1]
The dead included Maj. John A. Klinner, Capt. Ariana G. Savino, and Tech. Sgt. Ashley B. Pruitt of the 6th Air Refueling Wing at MacDill Air Force Base, Florida, and Capt. Seth R. Koval, Capt. Curtis J. Angst, and Master Sgt. Tyler H. [1]
The surviving jet, serial 63-8017, landed at Israel's Ben Gurion Airport immediately after the incident, images showing that half its tail was sheared off. [1] It arrived at RAF Mildenhall in the United Kingdom on Aug. 2 with a replacement tail, then left Mildenhall and finally arrived at Tinker on Aug. 3. [1]
[1] An Air Force spokesperson told The War Zone that the aircraft are "being inducted for programmed depot maintenance, where any damage patched by an Expeditionary Depot Maintenance unit will be fully repaired in conjunction with regularly scheduled 5-year maintenance." [1] "The current average for this regularly scheduled maintenance is 155 days, but it is reasonable to assume the timeline may be extended based on findings," the spokesperson said. [1]
The journey of each aircraft tells a larger story about what sustained air combat actually costs — not in headlines but in maintenance bays, replacement parts, and the slow, meticulous work of keeping old airframes in the fight.
The EDMX completed more than 200 repairs over the course of three weeks during the conflict, producing patches that let aircraft stay mission-capable long enough to return to Tinker for comprehensive work. [1] Two other Stratotankers — serial 59-1444 of the Ohio Air National Guard's 121st Air Refueling Wing and serial 63-8028 of the Alaska Air National Guard's 168th Wing — both made a temporary stop at Mildenhall covered in temporary shrapnel damage repairs before heading onward to Tinker. [1]
An Iranian attack on Prince Sultan Air Base in Saudi Arabia is said to have damaged five tankers, though the full scope of destruction from that strike and subsequent attacks remains unclear. [1] U.S. Central Command has declined to discuss battle damage, and a lack of commercial satellite imagery of the region has made independent assessment difficult. [1] The damaged tankers are among at least 40 aircraft damaged or destroyed during the U.S. conflict with Iran. [1]
Air Force Chief of Staff Kenneth S. Wilsbach told Congress in April that the service hopes to address losses through a supplemental funding request. "The procurement going forward is meant to increase the number of tails we have, especially in the fighter force, but it will also include bombers and tankers as well. So both the supplemental and the '27 budget is supposed to address those losses," he said. [1]
There is something worth sitting with in the fact that aircraft older than most of the people flying them are still being sewn back together and returned to service — that the logic of military aviation now depends on repair as much as procurement.
Every KC-135 now at Tinker has been in service for more than 60 years. [1] Executing a battle damage repair plan in the field to get a KC-135 back in the air is a good real-life exercise, one that could prove vital if a future conflict in the Pacific were to erupt. [1]
The war with Iran produced hard lessons about sustaining an aging tanker fleet under fire. How many more aircraft sustained damage that CENTCOM has yet to confirm remains an open question — but the repair queue at Tinker already suggests the answer is not small. [1]
